Stereo digital volume control:

A Crystal Semiconductor application

Stereo digital volume control:
Although the stereo digital volume contral Type CS3310 from Crystal Semiconductor is designed primarily for audio systems, it may also be used to upgrade existing systems by praviding programmable level control. These applications may include automatic test equipment and industrial control. It contains a 16-bit serial interface that controls two independent, low-distortion audio channels. The simple 3-wire interface provides daisychaining of a number of CS3310s for multi-channel audio systems. The device includes an array of well-matched resistors and a low-noise active output stage that is capable of driving a 600 Q load. The CS331 0 operates from +5 V supplies and has an input/output voltage range of +3.75 V.
